RIBBED KNITTED WEB.

To all whom it may concern:

Be it known that I, ROBERT W. SCOTT, a citizen of the United States,residing in Leeds Point, Atlantic county, New Jersey, have inventedcertain Improvements in Ribbed Knitted 1Webs, of which the following isa specification.

The object of my invention is to produce ornamental effects in ribbedknitted fabrics by special manipulation of the stitches of said fabrics.

In the accompanying drawings-Figure 1 is an exaggerated view of a pieceof ribbed knitted web in accordance with my invention, Fig. 2 is adiagram illustrating the arrangement and operation of certaininstrumentalities whereby the same can be produced, and Figs. 3 and 4are views illustrating certain of said instrumentalities.

Referring in the first instance to Fig. l of the drawing c represent thewales of one face of the web which may, for instance, be those producedupon the cylinder needles of the rib knitting machine, and b are thewales of the other face which may be those produced upon the dialneedles of the machine, the web shown constituting what is termed athree-and-three rib, that is to say, it has cylinder needle wales ingroups of three alten nating with dial needle wales in groups of three.In the present instance the ribs produced by the needles o are normalbut those produced by the needle wales c have eyelet holes formed inthem by transferring a stitch from the central needle wale of the rib toa wale on one side of the same, as shown at c, and then drawing a newloop d upon the needle from which the stitch has thus been transferred.

In order to better distinguish the ribs from one another I have, in thedrawing, shown the stitches constituting the ribs of one face in heavierlines than those constituting the ribs of the other face.

It will be observed on reference to Fig. l that the outer needle wales crecede from each other at the point where the eyelet hole is formed,consequently the rib of which these wales form part is alternatelydistended and contracted, the normal ribs formed by the needle walesbeing of uniform width but pursuing a waved or undulating coursecorresponding to the expansion and contraction ol' the ribs of the otherface, the expanded Specification of Letters Patent.

Application filed April 1, 1907, Serial No. 365,740.

Renewed July 6, 1909. Serial No. 506,214.

-instrumentalities for producing eyelet holes in the ribs in the mannerdescribed will be understood on reference to Fig. 2, in which a:represent cylinder needles for producing the wales c of the web, yrepresent dial needles for producing the wales b, and w represents atransfer point for conveying a stitch from one -v wale of a rib toanother wale of the same.

The transfer point w has a stem l, an outer end 2 in line therewith, adiagonally inclined or stitch-deiiecting portion 3 with shoulder 4 atthe base of the same, a short sub-stem 5 parallel with the main stem anda transverse neck 6 connecting said sub-stem to the main stem (see Fig.3). The needle from which the stitch is to be transferred should beprovided with a shoulder or offset, which, when the needle is projectedto an abnormal elevation, will engage and stretch the stitch last formedupon said needle, in order to permit of the entry of the outer end ofthetransfer point w into said stitch, the stem 1 of the transfer pointbeing radially guided in the needle dial or other convenient support ina plane co-incident with the vertical plane of movement of the needle.In the present instance the needle has an outwardly projecting loop 'uwhose upper member, when the needle is abnormally projected, engages thestitch and moves the same into proper position for the entrance of theouter end of the transfer point. Continued movement of said transferpoint then brings the stitch under the influence of the diagonallyinclined member 3 of the point, with the result that the yarnconstituting one side of the stitch is deflected laterally to such anextent as to overlie the plane of movement of the next adjoiningcylinder needle a, as shown in Fig. 2, said needle being then projectedinto position to engage the deflected portion of the stitch, whereuponthe transfer point is retracted, the transfer operation being completedby withdrawing the needle upon which the stitch was originally formed soas to cast off said stitch, the needle, however, being immediatelyrestored to action, in order to Patented Aug. 24, 1909.

Y ,aries of the eyelet hole.

If it is desired to form eyelet holes in the ribs of both faces of theWeb the cylinder may be provided With transfer points of the characterdescribed for action upon the dial needle stitches in a manner similarto that set forth in connection with the cylinder needle stitches.

When it is not considered important to mount the stem of the transferoint midway between the groups of needles o that member of the machinewhich carries said transfer point, said stem need not be in the plane ofthe outer end of the point, and thel transverse neck 6 can then bedispensed with, and, if desired, the transferred stitch may be distendedin both directions so as to engage With the Wale on each side of thesame by the use of duplex transfer hooks, such as are shown anddescribed in my Letters Patent No. 846,430 dated March 5, 1907.

The purpose of permitting the needle from which the stitch is to betransferred to retain its hold upon said stitch until the receivingneedle has entered it, is to cause the spreading of the stitch by thedischarging needle and thereby provide, for the entrance of thereceiving needle, an opening of larger area than would be presented ifthe stitch was cast from the discharging needle before said receivingneedle had entered it, for, in the latter case, the transfer point Woulddeflect the stitch directly from the upper edge of the knitted Web andwould thus tend to contract said stitch and render it more difficult forthe receiving needle to ass through the same. When such distentlon ofthe stitch is not desired, however, the needle from which the stitch isto be transferred may be constructed as shown in my Letters Patent No.834,763, dated October 30, 1906, With a stem at an angle to its shankand the stitch to be transferred can be deflected laterally to thedesired extent by a lateral shogging of the needle after the same hasbeen raised so as to be free from the control of the cylinder, or, evenin the latter case, distention of the stitch may be effected bycausing astraight point to be projected into engagement With the stitch beforethe shogging movement of the needle is effected, or the shoggingmovement may be imparted to such stitch-engaging point instead of to theneedle.

I prefer to carry out my invention in connection with that class ofribbed webs Which have three, or some other uneven number of Wales ineach of the ribs in Which the eyelet holes are to be formed, and totransfer the stitches from the intermediate Wale of the group in orderto locate the eyelet holes in the center of the rib, but my invention isapplicable to any ribbed Web having a plurality of Wales in a rib, andthe ribs in which no eyelet holes are to be formed may have but a singleWale if desired.

The production of eyelety holes in certain courses of a ribbed Web hasthe effect of expanding the Web to some extent at such courses, and thisreduces, to a corresponding degree, the elasticity of such portions ofthe Web. In order to lessen this expansion Without correspondinglylessening the number of eyelet holes formed in the Web, I prefer to formthe eyelet holes of successive rows in different Wales, thus the eyeletholes of the first roW in the Web shown in Fig. 1 are formed in thewales marked bm, While the eyelet hole of the second roW is formed inthe Wale marked fm.

Independently of the ornamental effects due to the distention andcontraction and to the Waving of the ribs of the web, eyelet holes, whenformed in ribs constituting the outer face of the garment, serve theirintended purpose better than eyelet holes formed in a plain Web, orbetween the 'ribs of the two faces of a ribbed Web, because the needleWales between which such eyelet holes are formed are supported free fromcontact With the skin of the wearer of the garment.

I claimzf 1. A ribbed knitted Web, having, in ribs of either face, aplurality of needle Wales and eyelet holes formed by transferringstitches from one of said Wales to another Wale or Wales of the set.

2. A knitted web, having, in ribs of either face, an odd number ofneedle Wales, and eyelet holes formed by transferring stitches vof theintermediate Wale of the setto a Wale on either side of the same.

3. A knitted Web having normal ribs on one face, and, on the other face,ribs containing a plurality of needle Wales With eyelet holes formed bytransferring stitches from one of said Wales to another Wale or Wales ofthe set.

4. A knitted Web having normal ribs on one face, and, on the other face,ribs containing an odd number of needle Wales With eyelet holes formedby transferring stitches of the intermediate Wale of the rib to a Waleon either side of the same.

5. A ribbed knitted Web, having, in ribs of either face, a plurality ofneedle Wales'and eyelet holes formed by transferring stitches from oneof said Wales to another Wale or Wales of the set, the eyelet holes ofone rib registering With the spaces between the eyelet holes of theadjoining ribs.

6. A knitted Web, having, on one face, normal ribs which follow a wavedor undulating course, and, on the other face, ribs, each containing aplurality of needle Wales, the latter ribs having eyelet holes formed bytransferring stitches from one Wale of the rib to another Wale or walesof the same, the eyelet holes of one rib registeringl with the spacesbetween the eyelet holes of the adjoining 1 ribs.

7. A knitted web7 having, on one face, normal ribs which follow a wavedor undulating course7 and, on the other face, ribs, eneh containing anodd number' of needle i either side of the same, the eyelet holes of onerib registering with the spaces between the eyelet holes of theadjoining ribs.

In testimony whereof, I have signed my 15 name to this speeiiieation, inthe presence of two subscribing witnesses.
